1. The order is to give 60 mg of Garamycin (gentamicin) IM every 8hr. The vial is labeled 80 mg/ 2 mL. How many mL will you give? ? mL = 2mL/80 mg X 60 mg/(1) = 12/8 = 1.5 mL 2. The patient is to receive 65 Units of a drug. The vial is labeled 50 Units per 2 mL. How many mL will you give? ? mL = 2 mL/50 units X 65 units/(1) = 130/50 = 2.6 mL 3. The patient is to receive 0.6 g of a drug. How many mg will you give? ? mg = 1000 mg/1 g X 0.6 g/(1) = 600/1 = 600 mg 4. The patient received 400 mL of f...
